Lithium Car Battery Hazards

Lithium batteries are the power behind our electronic gadgets and electric cars. They offer greater storage capacity than nickel-cadmium or lead batteries for a similar weight and size.

They use lithium ions moving between electrodes in contact with a separator and liquid electrolyte to produce electricity. However, they have been associated with battery fires due to their flammable chemical composition.

Benefits

Lithium batteries are renowned for their energy density, meaning they pack an incredible amount of power into a small and lightweight package. They’re used in a wide variety of applications due to this, and they can easily handle the power demands of many common electronic devices.

When a lithium battery is charged, an external electrical power source applies an overvoltage to the cell, forcing electrons to flow from the positive electrode through the electrolyte and to the negative electrode. This generates oxygen gas, which makes the battery flammable. However, the lithium ions in the electrodes remain safely separated from one another, and this process is not as dangerous as a typical lead acid battery fire.

As a bonus, lithium batteries don’t need to be watered like flooded lead-acid units. This eliminates the need to constantly check and replace the water level, which can reduce maintenance time and costs. Lithium batteries can also be mounted in any orientation without the risk of acid spillage. This is ideal for performance upgrades that are often inhibited by factory battery mount locations.

Lithium batteries also have a lower self-discharge rate than other rechargeable battery types. This means that they hold their charge much longer, allowing users to quickly replenish the battery when needed. This is a huge advantage for mobile devices and electric vehicles that might be unused for long periods of time, or for people who want to avoid the hassle of frequent recharging.

Drawbacks

The chemistry that makes lithium batteries work mercedes benz battery creates heat, which can lead to thermal runaway and a fire if the battery is not properly dissipating the heat. Oftentimes this can be due to mechanical damage or improper battery management circuitry.

Lithium batteries require a complex protection circuit that limits the peak cell voltage during charge and prevents the cell from dropping below 2 V on discharge. The cells also have a protective epoxy layer that stops metallic lithium plating from occurring on the anode. Despite the added safety, the batteries are fragile and are not as robust as some other rechargeable battery technologies.

One of the most significant drawbacks to using a lithium car battery is that they are more expensive upfront. However, the longer lifespan and recyclability make them a cost effective option over time. They can also be charged faster and hold a higher energy density than traditional lead acid car batteries. Additionally, the extra resting voltage of a lithium battery leads to less starter wear which can save you money in repair and replacement costs in the long run. This is particularly important for people who frequently drive over off-road terrain, as the added starting power will prolong the life of your starter motor. This can save you from getting stranded 30 miles away from a paved road with a dead starter motor.

Recyclability

As the demand for lithium car batteries grows, regulators and manufacturers are searching for ways to recycle these batteries at their end of life. However, most lithium car batteries are currently considered ignitable hazardous wastes that could potentially explode or catch fire if improperly handled at the end lithium ion car battery of their lives. This has prompted many manufactures to work with new designs that make them easier to recycle once they reach the end of their useful lives.

These new designs, such as those used by Alsym’s batteries, aim to eliminate flammable materials such as lithium and cobalt and replace them with alternative, non-hazardous raw materials. They also allow for the battery cells to be stacked on top of one another, increasing the energy density of the battery and the distance it can travel before needing to be recharged.

Most lithium batteries are recycled in large plants by shredding them and then melting or dissolving them into liquids so that they can be separated out and repurposed for other uses. Specialized battery recyclers recover a variety of valuable metals from Li-ion batteries, including nickel, cobalt, and manganese.

The European Union lists lithium (Li), cobalt (Co), and natural graphite as critical resources. This is partly because their availability is limited and because they can only be extracted from specific geological formations. Increasing the recycling rate for Li-ion batteries will help to reduce the need for these critical materials and lower the risk of supply shortages, but it is unlikely to fully offset the need for mining new raw materials.

Safety

Lithium batteries power everything from laptops and cellphones to electric vehicles, but they aren’t without risk. Fires attributed to lithium batteries have been on the rise in places like New York and San Francisco, with most of them causing structural damage.

While lithium batteries have built-in safety features that prevent thermal runaway, they can still be damaged or overheated. When this happens, the cells may degrade and start to self-combust. The resulting “stranded energy” poses risks of electric shock and battery reignition/fire, and it can be difficult for firefighters to extinguish these types of fires.

In order to help mitigate these risks, fire departments must be familiar with the specific characteristics of lithium batteries. They need to be aware that they can burn hotter and faster than other types of batteries, creating more challenging conditions for fire crews.

It’s also important that employees follow proper handling and storage guidelines when working with EV batteries. For example, they should keep the battery terminals covered to prevent short circuits, and they should never put them in a microwave or freezer. They should also use only approved chargers, and dispose of any swollen or dented batteries. Employees should also be vigilant for warning signs, including a change in color or odor, excessive heat, and leaking or venting gases. If they see any of these signs, they should evacuate the area and call 000 immediately.
